Macmahon Holdings, an Australian mining services company listed on the Australian Securities Exchange, has secured a three-year extension to continue providing mining services at the Byerwen coking coal mine in Queensland’s Bowen Basin, Australia. The agreement, announced recently, will add approximately A$900 million ($543.5 million) to Macmahon’s order book, reinforcing its long-term presence at the site.

The contract extension will continue service provisions, starting from October 2025.

The extension, effective from October 2025, builds on Macmahon’s existing operations at Byerwen, where its workforce and equipment are already deployed. No additional capital investment is needed beyond routine maintenance budgets, ensuring operational continuity. While the agreement’s core terms have been settled, final details are expected to be formalized by September 30, 2025.

The Byerwen mine is operated by Byerwen Coal, a joint venture between Australia’s QCoal Group and Japan’s JFE Steel. Since the mine’s inception in 2017, Macmahon has provided open-cut mining services, including loading, hauling, and crusher feed operations, employing over 800 workers on-site to support production.

Macmahon’s CEO and Managing Director, Michael Finnegan, expressed enthusiasm for the continued partnership, stating: “We are very pleased to continue as the mining contractor at Byerwen where we have worked closely with the team since the mine commenced operations in 2017. We will continue to refine the terms and conditions over the next few months with a focus on mutually beneficial outcomes that will enhance operational efficiencies on site.” He added: “The QCoal relationship and Byerwen project have been key to the Macmahon business stabilising over the last eight years. The teams are grateful and excited that they will have the opportunity to continue to develop that relationship on site and corporately.”

The Byerwen extension strengthens Macmahon’s role in Australia’s coking coal sector, a vital component of global steel production. The company’s long-standing collaboration with Byerwen Coal highlights its focus on operational reliability and partnership-driven growth. Finnegan also acknowledged the dedication of both Macmahon and Byerwen Coal teams, emphasizing their shared commitment to finalizing the contract terms.

Separately, in March 2025, Macmahon expanded its international portfolio by securing a contract with PT Citra Palu Minerals to provide underground mining services at the Poboya gold project in Sulawesi, Indonesia. This development complements Macmahon’s ongoing work at Byerwen, showcasing its versatility across different mining environments and reinforcing its position in the global resources industry.
